An overview of the sandfly fauna (Diptera: Psychodidae) followed by the detection of Leishmania DNA and blood meal identification in the state of Acre, Amazonian Brazil

Mem. Inst. Oswaldo Cruz; 115 (), 2020
BACKGROUND In Acre state, Brazil, the dissemination of cutaneous leishmaniasis has increased in recent years, with limited knowledge of the potential Leishmania spp. vectors involved. OBJECTIVES Here, data concerning the sandfly fauna of Brasiléia municipality, Leishmania DNA-detection rates and the ...

Abundancia y diversidad de vectores (Diptera: Psychodidae) en área de transmisión antigua de Leishmaniasis Cutánea en el nuevo mundo después de la construcción del gasoducto Bolivia-Brasil

The objective of this study was to determine the abundance and diversity of the species and their presumed vectorial role in the transmission of Cutaneous Leishmaniasis (CL). Research on sand flies (Diptera: Psychodidae) was carried out in two municipalities in the Ribeira River Valley in the State of Pa...

Ecology of phlebotomine sand flies in an area of leishmaniasis occurrence in the Xakriabá Indigenous reserve, Minas Gerais, Brazil

Abstract INTRODUCTION: Leishmaniasis is a complex vector-borne infectious diseases caused by protozoan parasites in the genus Leishmania and spread by hematophagous phlebotomine sand flies (Diptera: Psychodidae, Phlebotominae). The aim of this study was to investigate the phlebotomine fauna, endophily a...

Molecular validation of anthropophilic Phlebotominae sandflies (Diptera: Psychodidae) in Central Panama

Mem. Inst. Oswaldo Cruz; 114 (), 2019
Six Phlebotominae sand fly species are incriminated as biological vectors of human pathogens in Panama, but molecular corroboration is still needed. We aim at confirming the identity of Phlebotominae species documented as anthropophilic in Panama. Adult sandflies were collected from August 2010 to Februa...
